Xylome awarded a USDA SBIR grant to improve aquaculture

July 1, 2022 – The USDA SBIR program, administered by NIFA, awarded Xylome a grant to produce low cost omega-3 polyunsaturated fatty acids from yeast to improve the nutritional quality of aquaculture raised fish.


Xylome in the news: The Irreplaceable

June 23, 2022 – London Review of Books • Bee Wilson

A synthetic palm oil made by a fermentation process similar to brewing beer, which apparently looks like ‘an assemblage of golden-hued blobs’, waxy and odourless. It is made by an American tech company called Xylome, which has also created a sustainable alternative to biofuels using corn stover.

Palm oil is one of the most destructive ingredients you use every day. These startups are trying to replace it

January 27, 2022 – Fast Company • Adele Peters  

Xylome is beginning to work with brands to test an alternative called “Yoil,” produced by yeast, that’s almost identical to palm oil. “It’s basically a drop-in replacement,” says Xylome CEO Tom Kelleher.


Can Synthetic Palm Oil Help Save the World’s Tropical Forests?

January 5, 2022 – YaleEnvironment360 • James Dinneen  

Numerous startups are creating synthetic palm oil in the lab, hoping to slow the loss of tropical forests to oil palm cultivation. But palm oil is the most widely used vegetable oil, and producing a synthetic version on a large scale remains a daunting challenge.


The Global Aquaculture Challenge recognizes Xylome for innovation in aquaculture

October 5, 2021 Xylome won an international award for innovation in aquaculture. The 2nd Global Aquaculture Challenge recognized Xylome’s Yoil(TM)-NoFish technology as an innovative, inexpensive and sustainable process that will generate omega-3 fatty acids for use as aquaculture feed. The Yield Lab Asia Pacific Agtech Fund and Accelerator sponsored a global competition to identify the most promising technologies for sustainable aquaculture. Xylome’s innovation focuses on the production of high omega-3 fatty acids from fermentation byproducts using an engineered highly lipogenic yeast. Using Xylome’s technology, Aquafeed containing heat-treated yeast in combination with other ingredients could cost as little as $0.65 a pound compared to $0.95 a pound for traditional aquafeed. That price target is especially feasible when combined with a soy protein base. Details about Xylome’s participation in this competition can be found here.


Xylome describes sustainable technology for engineered oils from agricultural byproducts

September 10, 2020 Each year, the roughly 200 industrial ethanol plants in the U.S. collectively produce about 30 million metric tons (m.t.) of low-value waste stream called stillage containing water-soluble organics and corn fiber residues. Disposing of stillage is problematic. However, Xylome, a small business based in Madison, WI, has developed a way to use the waste stream as a consistent, stable feedstock for conversion to valuable products. The company has genetically engineered a novel yeast to enable this transformation.

Xylome awarded foundational patent on engineered yeast for lipid production

May 26, 2020 The U.S. Patent Office has recognized Xylome’s exclusive right to claims under US 10,662,448 for “Compositions and methods for producing lipids and other biomaterials from grain ethanol stillage and stillage derivatives”.

Lipogenic yeasts are modified to express, constitutively express, or overexpress numerous enzymes for lipid synthesis and substrate utilization. The yeasts in some cases are also modified to reduce or ablate activity of certain proteins. The methods include cultivating the yeast to convert low value soluble organic stillage byproducts into lipids suitable for biodiesel production and other higher value uses.


Xylome acquires Sarnaya to provide base for cosmetic applications

November 10, 2019 Xylome has acquired Sarnaya Skincare to provide the base materials for its skin cream. Xylome will begin production of yeast oil (Yoil™) at its contract facilities in Menomonee Falls, Wisconsin by May, 2021.


DOE selects Xylome to make biodiesel and higher value products from stillage fiber

September 4, 2018 The BioEnergy Technologies Office (BETO) within the Office of Energy Efficiency and Renewable Energy (EERE) informed Xylome that it’s application submitted in response to a Funding Opportunity Announcement (FOA) was selected for award negotiations. Xylome must match 20% of the total project costs, which total approximately $1.3 million. The objective of the project is to generate biodiesel and higher value products from stillage fiber. The broader impact and commercial potential of this project is to produce, the next generation of sustainable, renewable, clean burning, high energy density, transportation biofuels. The project includes commercial collaboration with two large industrial ethanol producers.


Xylome Corporation awarded U.S. Department of Agriculture Phase I SBIR grant

June 1, 2017 The US Department of Agriculture (USDA) awarded Xylome Corporation $100,000 for a Phase I Small Business Innovative Research (SBIR) grant to develop a Novel process for omega-3 oil production from agricultural byproducts. The grant, which started on June 1, 2017, focuses on metabolic engineering a yeast to produce omega-3 fatty acids for aquaculture.


Xylome Corporation awarded an SBIR Advance Award from Wisconsin for commercial and business development

March 1, 2017 The Wisconsin SBIR Advance program awarded Xylome $75,000 for commercial and business development activities within Wisconsin. This grant has enabled Xylome to attend two trade shows that brought in major customer leads. It has also supported customer research that led to a new prospective product line.


Xylome awarded NSF Phase II SBIR grant

Sept 20, 2016 Xylome Corporation was awarded $750,000 to develop a “Novel bioprocess for lipid production from industrial byproducts”. The two-year grant for $750,000, which started on October 1, 2016, will run through September 30, 2018.

The purpose of this Phase II project is to produce economically the next generation of sustainable, renewable, clean burning, high energy density, transportation biofuels. The proposed technology once successfully developed will enable existing biofuel producers to reduce their costs while increasing the value and diversity of their byproducts. It will convert their industrial waste products into tailored fatty acids suitable for biodiesel.
